VALVE-SPRING COMPRESSOR' Specification of Letters Patent.

Patented Aug. 3, 1920.

Application filed June 28, 1919. Serial No. 306,036.

To all whom it may concern Be it known that I, CYRUs Evnni'r'r a citizenof the United States, residing at idney, in the county of Champaign andState of Illinois, have invented new and useful Improvements inValve-Spring Compressors, of which the following is a specification.

This invention relates to a valve spring compressor, and embodies, amongother features fixed and relatively movable levers each having aconcaved or dished end portion which engage the tappet spring supportingwasher respectively in a manner to prevent casual displacement of thetool when in use; means beln provided'to hold the movable lever inad]usted position, and the spring compressed, thus permitting the use ofboth hands for other work.

The nature and advantages of the invention will be better understoodwhen the following detailed description is taken in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawings forming part of this specification like numerals ofreference indicate similar parts in the several views and wherein:

Figure 1 is a plan view of the tool constructed in accordance with myinvention.

Fig. 2 is a side elevation showing the man ner of compressing the springand holding the parts in their given position.

Fig. 3 is a transverse vertical sectional Y1e\V.

The tool forming the subject matter of my invention comprises a lever 10which may be constructed of anyconsiderable material and desired length,and provided with a standard l1 rising from a point approximately midwaybetween the ends thereof. The standard is provided with a series orplurality of superimposed openings 12, in any.

susceptible of being rocked upon the pivot 13. 7 One end correspondingextremity of the respective lever, is provided with an enlarged centralopening-'16 which communicates with a slot 17 which opens at the edge orperiphery of said end. These end portions are substantially circular,and each is concaved or dished to effectively engage the component partof the valve for the purpose intended. The concaved or dished portion ofthe lever 10 is reversely disposed with regard to the similar portion18. of the lever 14 as shown in Fig. 2. In practice the slotted terminalof the lever 10 is fitted around the tappet 19, the concaved portionengaging the tappet in a manner to prevent relative movement of thelever 10. The corresponding extremity of the lever 14 is as- .sociatewith the valve stem in a manner so that the spring supporting Washer 20is snugly fitted or seated withln the concavity 18. As above stated, thelever 10 remains fixed or stationary, while the lever 14 is rocked uponthe pivot 13 by depressing the free end of the lever, during which timethe spring 21 is compressed by very little effort.

With a view of maintaining the lever 14 in adjusted position, and thespring compressed, thus permittin the use of both hands for other work,provide the lever 10 with spaced apertur'ed lugs 22, between which oneend of a rack bar 23 is fitted and suitably secured. The teeth 24 ofsaid bar project from one side thereof at an inclination toward thelever 10. The lever 14 is provided with an elongated opening or slot 24which receives the bar 23, and one edge of this slot is engagedfby theteeth of the rack bar for holding the lever in any given position. Itwill be noted, that the pivot 13 can bearranged at any desired pointupon the standard 11, to permit a proper leverage to be obtained forsprings of different strength or tension.

While I have shown and described what I consider the preferredembodiment of the invention, I desire to have it understood that I donot limit myself to the exact details herein shown, and that suchchanges may be resorted to when desired as fall within the scope of whatis claimed.

What I claim is A valve spring compressor comprising a base, a standardrising therefrom and fixed to the base, said standard having a pluralityof openings, a pivot adapted to beinterchangeably fitted 111 saidopenings and to project beyond the opposite sides of the standard, alever ot a length substantially equal to that of the base, said leverbeing curved from the ends and having an elon-' ing oppositely dishedand forked, a rack bar rising from the base in parallelism with thestandard, said rack bar being pivotally mounted upon the base, a leverhaving a second elongated slot for the reception of therack bar, and theedge of the latter mentioned slot being adapted to engage the teeth ofsaid bar for holding the lever fixed in a 20 given position.

In testimony whereof I affix my signature.

CYRUS EVERITT.
